"It was horrible, Neil," Manchin told host Neil Cavuto on Fox News. "No one should approve of that, and I hope she doesn't talk to her son that way either. You know, what can you say? I can't in any way condone that. That's not how we act in West Virginia. It's not how we talk about public leaders."

"We might disagree with each other, but we try to get through it, we try to find a pathway forward. To act like that is awful and to speak like that is even more deplorable. I am so sorry. I want to apologize to all Americans, any sitting Congress person - there's 535 of us there, 100 senators and 435 Congress people. We should have better manners than that, I assure you."

Tlaib, one of the first two Muslim women to be elected to Congress, has caught flak for comments she made at a MoveOn.org rally near Capitol Hill on Thursday night.

"When your son looks at you and says, 'Momma, look, you won. Bullies don't win.' And I said, 'Baby, they don't.' Because we're going to go in there and impeach the motherf---er," Tlaib said as the crowd cheered her on.

"I thought her comments were disgraceful," Trump said in the Rose Garden, adding he thought the remarked "dishonored" the country and Tlaib's family.

Manchin is not the only Dem to call out Tlaib's profanity.

"You cannot accomplish very much of anything unless you have civility and show respect for your colleagues. And I think those kind of comments do not take us in the right direction," said House Oversight and Reform Committee Chairman Elijah Cummings (D-Md.).

While Speaker Nancy Pelosi (D-Calif.) told MSNBC she "wouldn't use that language," she added that she's "not in the censorship business."

Tlaib doubled down on her remarks Friday and issued a statement reiterating her call for the president to be impeached.

"Congresswoman Tlaib was elected to shake up Washington, not continue the status quo. Donald Trump is completely unfit to serve as president. The Congresswoman absolutely believes he needs to be impeached. She ran and won by making this very clear to the voters in her district," her office said.

"I will always speak truth to power. #unapologeticallyMe," Tlaib said in a tweet.
